Weigle reactivation of diploid M13 phage. 1984

J E LeClerc, and N L Istock

The limited ability of ultraviolet (UV)-irradiated E. coli cells to W-reactivate UV-irradiated, single-stranded DNA phages fd and M13 was investigated. The kinetics of induction for W-reactivation of UV-irradiated fd phage are different from that for other SOS functions. W-reactivation of UV-irradiated M13 phage was studied using phage particles that contain at least two single-stranded DNA genomes. No effect on the extent of W-reactivation of diploid phage was observed, compared to that of normal haploid phage, indicating that the mechanism of W-reactivation of single-stranded DNA phages does not involve recombination between partially replicated genomes.

D014466 Ultraviolet Rays That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
